Why Is My Dog Peeing in the House? 8 Causes and a Flowchart

To stop dog from peeing in house, you have to find the cause first. A training schedule won’t fix a bladder infection, and a scolding won’t fix a dog who is stressed. Vets group indoor peeing into four causes: a training gap, illness, fear or anxiety, and marking.

Step 1: Check for red flags before anything else

See a vet before you retrain if you notice any of these:

• Blood in the urine, or pink or red urine.
• Straining, crying, or only drops coming out.
• Peeing much more often, or larger amounts.
• Drinking noticeably more water.
• A house-trained adult suddenly having accidents.
• Leaking or wet patches where your dog slept.

If you see any red flag, vet first. Pause the reset until your vet gives the all-clear.

The flowchart: what does the accident look like?

If there are no red flags, read the pattern:

1. Full puddle on the floor, often near the door or after long gaps: training or schedule gap.
2. Small amounts on upright things like walls, furniture or bags: marking.
3. Dribbles at greetings, such as crouching or rolling over: submissive urination.
4. Only when alone, or after a big change: talk to your vet or a behaviorist.

The 8 causes at a glance

What you see	Likely cause
Full puddles, often near the door or after long gaps	Training or schedule gap
Small amounts on upright things, new objects, visitors’ bags	Marking
Dribble when greeted, crouched or rolling over	Submissive urination
Pee while jumping at greetings, mostly under 1 year	Excitement urination
Only when left alone, with chewing or howling	Possible separation distress (vet or behaviorist)
Wet bed or wet patch where the dog slept, often a spayed female	Incontinence (vet)
Senior dog pees right after coming in, seems lost	Possible cognitive decline (vet)
Started after a move, new baby, new pet or new work hours	Stress or change

How to stop dog from peeing in house, cause by cause

• Training gap: restart as if your dog were a puppy, with one toilet spot, trips before they need to go, supervision and a log.
• Marking: vet check first. Supervise and redirect with a happy voice or a toy, block favorite targets with gates or furniture, and use a leash in new places. Neutering may reduce marking in males, but it doesn’t always work.
• Submissive urination: it isn’t deliberate, and scolding makes it worse. Greet calmly, crouch side-on, avoid eye contact and leaning over, and ignore your dog for about 5 minutes when you arrive.
• Excitement urination: keep arrivals boring, greet outdoors and use low voices. It usually fades as dogs mature.
• Stress, change or anxiety: treat the cause with your vet or a behaviorist.
• Incontinence or cognitive decline: these are vet matters, not training problems.

Keep a 3-day log

Record every pee, inside and out, plus water, meals, sleep and triggers. A few lines show the time, place and what happened just before. Bring the notes to your vet if a red flag shows up. Our post on seven signs it’s time to see a vet lists what to watch, and the adult and rescue dog plan covers retraining.

Whatever the cause, never punish, shout or rub a nose in a mess, and clean accident spots with enzymatic cleaner so the smell doesn’t draw your dog back. Never use bleach or mix cleaners.
